If two cars leave Las Vegas,one traveling east and the other west.after 3 hours they are 297 miles apart.If one car is traveling 5 mph faster than the other, what is speed of two cars
**
let x=speed of one car
x+5=speed of other car
distance=speed*travel time
3x+3(x+5)=297
3x+3x+15=297
6x=297-15=282
x=282/6
x=47
x+5=52
speed of one car=47 mph
speed of other car=52 mph
